Synergies are thought to be the building blocks of vertebrate movements. The inability to execute synergies in properly timed and graded fashion precludes adequate functional motor performance. In humans with stroke, abnormal synergies are a sign of persistent neurological deficit and result in loss of independent joint control, which disrupts the kinematics of voluntary movements. This study aimed at characterizing training-related changes in synergies apparent from movement kinematics and…

Stroke-induced synergistic phase shifting and its possible implications for recovery mechanisms
The finding that timing differences between joints in pathological movements are comparable to differences that were observed by other researchers for normal, able-bodied movement synergies suggests that pathological synergies are spinal in origin.
Upper Limb Joint Space Modeling of Stroke Induced Synergies Using Isolated and Voluntary Arm Perturbations
The primary goal of this research is to model synergy and quantify it in a comprehensive and mathematically tractable form and this approach may have applications in diagnostic and treatment algorithms for use in rehabilitation robots.
Alterations in upper limb muscle synergy structure in chronic stroke survivors.
The results suggest that an impaired control of the individual deltoid heads may contribute to poststroke deficits in arm function.
The generalization of motor recovery after stroke: Assessment within and outside the training workspace
Stroke patients exhibit a reduced ability or incapacity to selectively activate muscle fibres and consequently motor performance is impaired. The best behavioural outcomes after stroke are associated
Effects of early and intensive neuro-rehabilitative treatment on muscle synergies in acute post-stroke patients: a pilot study
The hypothesis that muscle synergies reflect the injury of the cerebrovascular accident and could document the effects of the functional recovery due to a suitable and customized treatment is supported.
The Investigation of Motor Primitives During Human Reaching Movements and the Quantification of Post-Stroke Motor Impairment
The goal of this thesis was to examine the neurological control of movement in healthy individuals and apply these findings to the further investigation of chronically motor impaired stroke patients and to provide clinicians with a more reliable, easy to use, and inexpensive approach to quantify post-stroke motor impairment.
The effect of repeated measurements using an upper extremity robot on healthy adults.
Outcome measures of the MIT-MANUS proved to be reliable yet sensitive to change in healthy adults without motor learning over the course of repeated measurements, and robotic measurement ability to differentiate between similar but distinct tasks was demonstrated.
Reducing abnormal synergies of forearm, elbow, and shoulder joints in stroke patients with neuro-rehabilitation robot treatment and assessment
The robot-assisted therapy indices (variation of forearm pronation/supination torque, and co-activation of elbow and shoulder muscles) reveal a significant decrease of abnormal synergies after 4 month s of robot- assisted treatment and a slight regression in the following 4 months.
Dissociating Sensorimotor Recovery and Compensation During Exoskeleton Training Following Stroke
The quality of arm movements typically improves in the sub-acute phase of stroke affecting the upper extremity. Here, we used whole arm kinematic analysis during reaching movements to distinguish


Compensatory strategies for reaching in stroke.
It is discussed the possibility that there is a critical level of recovery at which patients switch from a strategy employing new degrees of freedom to one in which motor recovery is produced by improving the management of degrees offreedom characteristic of healthy performance.
Deficits in the coordination of multijoint arm movements in patients with hemiparesis: evidence for disturbed control of limb dynamics
It is argued that the spatial abnormalities are consistent with an impaired feedforward control of the passive interaction torques which arise during multijoint movements and are hypothesized to reflect a degradation of the internal representation of limb dynamics that occurs either as a primary consequence of brain injury or secondary to disuse.
Quantification of force abnormalities during passive and active-assisted upper-limb reaching movements in post-stroke hemiparesis
A method for measuring abnormal upper-limb motor performance in post-stroke hemiparetic subjects, which could complement currently used measurement tools for the evaluation of subjects during recovery from stroke, or during therapeutic interventions.
Combinations of muscle synergies in the construction of a natural motor behavior
It is shown that combinations of three time-varying muscle synergies underlie the variety of muscle patterns required to kick in different directions, that the recruitment of these synergies is related to movement kinematics, and that there are similarities among the synergies extracted from different behaviors.
Handedness: dominant arm advantages in control of limb dynamics.
The purpose of this study was to further investigate interlimb differences in coordination through analysis of inverse dynamics and electromyography recorded during the performance of reaching movements, and propose that distinct neural control mechanisms are employed for dominant and nondominant arm movements.
Forward and backward axial synergies in man
It was found that upper trunk movements are accompanied by movements of hip and knees in the opposite direction, resulting in a slight displacement of the center of gravity projection on the ground.
Evidence for a dynamic-dominance hypothesis of handedness

The results support the dynamic-dominance hypothesis, indicating that interlimb asymmetries in control arise downstream to visuomotor transformations, when dynamic variables that correspond to the forces required for motion are specified.
Proprioceptive control of multijoint movement: unimanual circle drawing
Abstract The present experiments addressed whether proprioception is used by the central nervous system (CNS) to control the spatial and temporal characteristics of unimanual circle drawing. Circle
Differences in control of limb dynamics during dominant and nondominant arm reaching.
Findings strongly suggest that distinct neural control mechanisms are employed for dominant and non dominant arm movements, however, whether interlimb differences in neural strategies are a consequence of asymmetric use of the two arms, or vice versa, is not yet understood.
Motions or muscles? Some behavioral factors underlying robotic assistance of motor recovery.
Initial insights about the process of upper-limb behavioral recovery that have emerged from robotic therapy work indicate that movement coordination rather than muscle activation may be the most appropriate focus for robotic therapy.
